GEORGE IV. HART, OF AURORA, INDIANA.

DUMPING-CAR.

To all whom it may concern:

Be it known that I, GEORGE W. HART, of Aurora, Dearborn county, Indiana, have invented a new and useful Improvement in Dumping-Cars; and I hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention is particularly intended to facilitate the loading of locomotive tenders, its leading feature of novelty consisting in the peculiar construction and operation of the movable floor.

In the accompanying drawings, Figure 1 is a side elevation of the car mounted on its track; the floor being extended. Fig. 2 is a vertical longitudinal section representing the floor half retracted.

When employed for loading tender the car is supported on an elevated track or way which may consist of an elevating turn table X, permanent way Y, and vibrating way Z; the latter so balanced that the impact of the advancing car throws it into the position indicated by red lines, thus affording a support which projects immediately over and at the proper height above the tender.

In the present illustration of my inven tion the car runs upon flanged whels B, C, and is propelled by means of a crank E, and pinions D, the latter gearing with cogged flanges of the wheels C.

The floor of the car consists of a set of slats 1, 2, 3, at, 5, 6, hinged together by their edges. Spurs H, projecting from these slats enable them to rest upon lugs I, which project inward in a horizontal range from each side of the car body.

J, is a reel of form and size to correspond with the number and breadth of the slats composing the floor, the slat 1, being, at tached to one of its facets. The axis of the reel is journaled in flanged rollers K, which run on ways L, fixed longitudinally on the frame A.

M, is a hand whel running loosely on the axis of the reel J, and carrying with it a pinion N, which gears in a rack 0, attached to the frame A, at the side of one of the ways L.

P, is a dog (turning on the axis of the Specification of Letters Patent No. 18,743, dated December 1, 1857.

reel J which engaging in the rack 0, prevents the retraction of the reel until it is released.

The operation is as follows.The loaded car having been run forward over the tender by means of the crank E, the dog P, is elevated and the hand wheel and pinion M N, rotated in the direction of the arrow Figure 1, the rack O, carrying them toward the rear of the car and with them the reel J, which the attachment of the slat 1, causes to rotate in the direction of the arrow Fig. 2. The slats are thus one by one disengaged from the lugs I, and wound onto the reel, resulting in the discharge of the load, either in a body, or in such quantities and at such speed as may be desired. Vhile this is taking place the car may be shifted by means of the crank E, or the discharge may at any moment be arrested and the car removed to another spot to deliver the remainder 0f the load. In this way the contents of the car may be deposited in any manner of distribution desired. The lugs I, afford firm support to the floor from both above and below and as no slat can leave the support of its lug until liberated by the removal of the slat next in front of it, the floor is stiff and secure when extended and the retraction of the reel prevented by the dog P.

The following points of superiority are combined in this machine in an eminent deg1'ee:1st, stability of the floor when in use; 2nd, its entire and compact removal so as not to obstruct the discharge or motion of the machine; 3rd, ease of manipulation; 4th, facility for discharging in successive portions subject to graduation by the operator.

I claim as new and of my invention herein In the described combination with the reel J, the slatted folding floor 1, 2, 3, t, 5, 6, supported and operated substantially in the manner set forth.

In testimony of which invention I hereunto set my hand.

GEORGE IV. HART.
